Cummins Inc. announced Wednesday, Aug. 13, that it will add selective catalytic reduction (SCR) aftertreatment to its heavy-duty products for 2010 to deliver the best fuel efficiency for its customers.
Cummins says it will combine recent advancements in catalyst technology with its engine systems, providing customers with significant fuel economy improvements, in addition to meeting the near-zero emissions levels required by the Environmental Protection Agency’s 2010 regulations. Cummins Emission Solutions, a provider of SCR systems, will supply integrated exhaust aftertreatment systems for Cummins heavy-duty and midrange engines.
As previously announced, Cummins’ heavy-duty ISX engine family will incorporate the XPI fuel system, cooled exhaust gas recirculation, the Cummins VGT turbocharger, the Cummins particulate filter and advanced electronic controls designed to enhance performance, fuel economy and reliability.
“Cummins’ expertise in engine system integration means that we have the capability to make the engine systems and aftertreatment technologies work together seamlessly,” said Steve Charlton, vice president of heavy-duty engineering for Columbus, Ind.-based Cummins. “The addition of the new SCR catalyst technology ensures that Cummins will deliver the best fuel economy in the industry and total operating cost benefits to our customers.”
“This move demonstrates Cummins’ ability to adapt to a changing environment by leveraging technology advancements from our midrange engine development and Cummins Emission Solutions,” said Ed Pence, vice president and general manager of Cummins’ Heavy-Duty Engine Business. “Our 2010 engine development is progressing on plan, and customers can depend on Cummins to deliver these new products on time, with the reliability, performance and fuel economy that they have come to expect from us.”
